A Google spokesperson explains:
Promoted pins in navigation are not new – they let people see relevant ads for businesses like gas stations, restaurants, and stores along their route. To avoid driver distraction, these ads do not pop up, expand only if they’re tapped on, and disappear quickly after a short time.
Too late. Already download OSM for the first time in years. I deliver all day long, and as much as I hated them, gmaps was worth it until now.
